Channel catfish immunity enhancing feed

Abstract

The invention discloses a channel catfish immunity enhancing feed, which comprises the following components in parts by weight: 5-14 parts of meat and bone meal, 15-25 parts of rapeseed meal, 20-40 parts of de-hulled soybean meal, 0.2-0.5 part of choline chloride, 15-22 parts of wheat middling, 0.5-1 part of soybean oil, 0.2 part of vitamin premix, 0.15 part of mineral premix, 1-2 parts of calcium dihydrogen phosphate, 0.01-0.03 part of plant enzyme, 0.05-0.1 part of cholate substances, 0.03-0.06 part of a toxin adsorbent, 0.1-0.3 part of a natural plant compound and 0.1-0.3 part of a polysaccharide compound. According to the immunity enhancing feed disclosed by the invention, nonspecific immunity of the channel catfish is enhanced through various compounds, and through reasonable proportioning of various natural plants and the polysaccharide components, nonspecific immunity of the channel catfish is significantly improved and infection resistance of the fish is enhanced; and meanwhile, growth performance of the fish is improved and a food coefficient is reduced.

Description

technical field [0001] The invention relates to the field of feed, in particular to an immune-enhancing feed for channel catfish. Background technique [0002] Channel catfish (Ictalurus Punctatus) belongs to Siluriformes (Siluriformes) and Ictaluridae (Ictaluridae). The meat is tender, without intermuscular spines, rich in protein and vitamins, and delicious in taste. It is a high-quality fish that is popular among farmers, processors and consumers. my country has promoted breeding in more than 20 provinces and cities since the success of artificial breeding in 1987. [0003] In the intensive breeding mode of channel catfish, high stocking density is the basis for obtaining high breeding returns. Feeding high-grade feed can promote the growth of channel catfish, shorten the breeding cycle, and achieve early market launch. However, in the process of long-term feeding of high-grade feed to ensure that the channel catfish has a good growth advantage, the physical weakeni...

AI Technical Summary

Problems solved by technology

However, in the process of long-term feeding of high-grade feed to ensure that the channel catfish has a good growth advantage, the physical weakening of the channel catfish is also serious. The main symptoms are loss of appetite, dull body color, and white or yellow liver. "Mottled", enlarged gallbladder, pale yellow bile, etc.; when the temperature difference changes or the water quality is unstable, the susceptibility of channel catfish to pathogenic bacteria increases, and sporadic diseases often occur. In severe cases, the average death rate of channel catfish per mu is as high as 70 -100 tails, the economic loss caused cannot be underestimated

In view of the weakening of channel catfish's physique, the use of antibiotics mixed with feed for oral administration is not only inappropriate, but will further induce problems such as physical decline, drug residue and water pollution of channel catfish; other commercially available health care drugs are often difficult to achieve due to lack of specificity ideal health effects
